We are using a 5329 processor and our (default isr) system hangs when "undefined" memory is addressed.

I have tried to use the Address error ISR( at Vector 3) with no success.

I do not get the interrupt when I address the non-existent memory. Here is the code I use to install the interrupt handler. It does show in the EDS Client.

volatile MCF5329_STRUCT_PTR mcf5329_ptr;

mcf5329_ptr = (MCF5329_STRUCT_PTR) _PSP_GET_MBAR();

if (_int_install_isr( (uint_32)MCF5329_EXC_ADDRESS_ERROR,

			(uint_32)MCF5329_EXC_ADDRESS_ERROR,
			&AddressErrorInterrupt,
			(void*)&Dummy_Data) == NULL)

{

printf("MCF5329_EXC_ADDRESS_ERROR _int_install_isr failed");

}

_mcf5329_int_init(MCF5329_EXC_ADDRESS_ERROR, CWD_INT_LEVEL, TRUE);

I also tried the Core bus error interrupt at Source 62 in INTC0. Here is its code. As soon as the interrupt is enabled the ISR is called, even though I feel I cleared it.

_INT_DISABLE();

volatile MCF5329_STRUCT_PTR mcf5329_ptr;

mcf5329_ptr = (MCF5329_STRUCT_PTR) _PSP_GET_MBAR();

	uchar SCMISR = mcf5329_ptr->SCMISR;
	mcf5329_ptr->SCMISR = SCMISR; // Clear Bus Error and core watchdog Interrupts

if (_int_install_isr(

			(uint_32)MCF5329_INT_CFE,
			&CFEInterrupt,
			(void*)&Dummy_Data) == NULL)

{

printf("MCF5329_INT_CFE _int_install_isr failed");

}

_mcf5329_int_init(MCF5329_INT_CFE, CWD_INT_LEVEL, TRUE);

//	mcf5329_ptr->SCMISR = 2; // Clear and enable Bus Error

mcf5329_ptr->CFIER = 1; // ENABLE Core Fault Interrupt

_INT_ENABLE();
